I can't see them doing another book in the New D52 continuity you"d have too many.

It's like 99% gonna be in the New 52. Batman: The Dark Knight has nothing to do with the Dark Knight series. This likely won't either. WB don't feel the need to cross over their media for films with DC's publishing.
